Incorrect wxWidgets Version

From Audacity Wiki

Warning icon This page is to inform users of Audacity 2.x of usability problems if it is built with wxWidgets 3.0 or later. This affects for example the packaged Audacity 2.0.6 supplied by Ubuntu 15.04.

You can look at the About Audacity dialog then the Build Information tab to check the version of wxWidgets that was used.

Audacity 2.x below 2.1.2 requires wxWidgets 2.8.12

You most likely reached this page from an incorrectly built version of Audacity that uses wxWidgets 3.0 or later.

Audacity 2.x below 2.1.2 should be compiled with the previous stable release of wxWidgets (2.8.12) which is still available on http://wxwidgets.org/downloads/. Ubuntu and Linux Mint users who do not want to compile Audacity are recommended to try installing an unofficial PPA build of Audacity 2.1.0 or 2.1.1 release compiled against wx2.8.12.

The developers have been fixing Audacity bugs when using wx3, so that the next 2.1.2 release of Audacity will support and require wx3.0.2 rather than wx2.8.12. For those using Audacity HEAD compiled against wx 3.x, please see below for the remaining wx3 problems that we know about (for all platforms).

2.1.0 and 2.1.1 stable release PPA's built against wx2.8.12

For users of Ubuntu 12.04, 14.04, 14.10, 15.04 and 15.10, also Linux Mint 13 and 17 there is a recommendable PPA of Audacity 2.1.0 or later releases built against wx2.8.12: https://launchpad.net/~ubuntuhandbook1/+archive/ubuntu/audacity. FFmpeg support is included and is known to work in Ubuntu 15.04, but does not export correctly in Ubuntu 14.10.

Uninstall the packaged version of Audacity before installing the PPA.
